DUMPING-CAR.

Specification of Letters Patent. Patented June 13, 1911.

vApplication filed November 30, 1908. Serial No. 465,343.

To all whom it may concern.

lie. it known that. I, AxToN Brenna, of Columbus, in the county of Franklin and State of Ohio have invented certain new and useful improvements in Dumping-Cars; and l do hereby declare the following to be a full. clear. and exact description of the invention. such as will. enable thers skilled in the art to which it: appertaius to make and use. the same.

This invention relates to dumping ears, the hnprorementsbeing direr'rted particularly to nmans for operating dropdoors for hopper bottom ears. and the object:- of my present invention is to provide simple and elticient means located (mutt-ally between the sides oi the car and having portions thereof supp rted by means inhn'mediate the. members oi the central lor j nilinahgirder for elleetually closing the doors and permitting them to open. I

\l'ith this object in view the invention con sists in certain novel feature of construction and (Olllllllltlllt' llS of parts as hereinafter setl'orth and pointed out in the claims.

In the :u-eom ninyiug drawin s, Figure l is a longitudinal sertion of a portion of a hopper bottom car :l win; the application 0.1. Iu Y innn'oreunruts thereto. Fig. 2 is a transverse sectional view of the same. Pig. 3 is a i1':r niit:1l' sectional view illustratin a modil'ivation. Fig. 4 if: a cross setj'tion showing the relation of the hours '1? to curb ther and Fig. is a plan \lt'tW.

l,--l rvrn J-scnt the inclined sides of the hopper ottom of a car and 2. 3, illustrate drop-doors which are hinged at. their uter edges to the lower ends of the said iueliuml sides of the hopper bottom. The tit'wl'S .u. 3 ar arranged in pairs at reqmetirc sides of the center girde'r and much door -3 is pro- Vidcd at its free mtg-o with a seat -.l whit-1n when the doors are clonal underlies the free edge of the opposite dour so that. the same means which sup 'iorts the doors 3 will also be utilized to support the doors The doors 2: are connected by a cross member or angle bar 5 secured to the under faces of said doors an passing under the center girder.

Between the center girder members 6, stiti'eners 7-8 are secured and spa-red apart a distau e somewhat. greater than the lengthof a door. To the stitl'eners 7-8 the upper ends of arms 9 of an inclined gu de br elret i 10 are secured, said guide brackets being thus disposed in a plane belowthat of the center girder. Similar guide brackets 11 are loeated inproximity to the sides of he l car and the se'ies of guide'braeliets serve to support an operating shaft 12,- the latter being provided at. a point near its center with a roller 13 to run on the guide bracket 10. The shaft. 12 is also provided with a drum 14 which, if desired may be made with a Spiral groove. A. chain 15 is secured at one end to the drum l and adapted to wind upon the latter. From the drum l t the chain 15 passes over a pulley l6 havin; its journalsmounted in lugs 17 projectiu; from the upper portion of the slitteuer 7. and from said pulley 16 the chain 15 passes downwardly and is connected with i an eye 11' on the cross member or angle bar I 5 secured to the doors 2 near the free edges of the latter.

Each door 3 is provided on its under side with a rack-bar 1S and with thisrack-bar, a pinion 19 secured to the shaft. 12 is adapted to mesh as hereinafter deseriljied.

When the. doors are open the operating shaft. i2- will be. disposed at the lower part of the guide-wars 10 and 11 and therefore an appreciable distance below the plane of the closed doors.the. pinion 19 on said shaft being hunted outwardly beyond the Vertical plane of the hinge-connection hetween the doors 3 and the inclined plate. or side 1 of the hopper bottom. The shaft 12 and tin doors 2-3 may be held in the positions shown in Fig.1 by any suitable do vices located at the side of the car and adapted to engage said shaft.

When the doors shall have been dropped so that the will assume the dotted line positious shown in Fig. l, and it, 'is desired to close said doors. the operator will pro ,-eed

ing means (not shown) of th halt 12 he will rotate said shaft so as to wind the chain 15 thereon and thus raise both doors 2 to closed position. When this shall have been accomplished. the continued rotation of this shaft 12 and the further winding of the chain thereon, will cause said shaft to ride upwardly on the inclined guide 10,-during which movement the pinions 19 will engage the racks 18 on the doors 3 and this will insure the positive engagement between the shaft and the doors and as the shaft moves as follows: 'r-rlrer having released the lock-- toward the upper end of the inclined guide 10 the doors will he moved upwardlj' totheir closed position and the seats t of said doors 3 will become disposed under the tree edges 01 the doors '2. At this time the shaft 1; will he at the inner end of the guide hmclu-t 10 and the doors will be supported and eti'ectually locked in their closed positions: by the action of the operating shaft. I

if desired the operating shatt may be pro rided with more than one pinion and the doors 3 with a corresponding nnmher of rack bars. In Fig. 2 of the drawing 1 have shown two pinions and tw l'tl(i('l)ill' for each door 3. I In the con truction shownin Fiir. 3 the raclhars and pinions are dispensed itlt and two guide-brackets 2th are secured respec-tive'rtto the center girder memhers and ach is provided with a series of perforations 21, with which spur wheels 22 mesh. These spur wheels a re' secured to the operating shaft 1". and a drum 23 is secured to said shaft between the spur wheels. The drum is pret'crahly ;rroored and ha sceured thereto a chain. such as shown in Fig. 1, but with the arrangement shown in Fig. 3, the chain is wound upon the drum in the reverse direction to tl-at'shiiwn in Fig. 2.

Other changes might he made in tin-de- =titiiS if construction ot Ht invention without'departin; from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise structural details herein set forth.
